He called Gwrhyr Gwalstawt Ieithoedd, because he knew all tongues.
He called Gwalchmai, the son of Gwyar, because he never returned home without achieving the adventure of which he went in quest. He was the best of footmen and the best of knights. He was nephew to Arthur, the son of his sister, and his cousin.
And Arthur called Menw, the son of Teirgwaeth, in order that if they went into a savage country, he might cast a charm and an illusion over them, so that none might see them whilst they could see every one.
They journeyed on till they came to a vast open plain, wherein they saw a great castle, which was the fairest in the world. But so far away was it that at night it seemed no nearer, and they scarcely reached it on the third day. When they came before the castle they beheld a vast flock of sheep, boundless and without end. They told their errand to the herdsman, who endeavoured to dissuade them, since none who had come thither on that quest had returned alive. They gave to him a gold ring, which he conveyed to his wife, telling her who the visitors were.
On the approach of the latter, she ran out with joy to greet them, and sought to throw her arms about their necks. But Kay, snatching a billet out of the pile, placed the log between her two hands, and she squeezed it so that it became a twisted coil.

They entered the house, and after meat she told them that the maiden Olwen came there every Saturday to wash.
